Backslash in the end of comment lines in C/C++

Question

Does your editor/ide highlight that a++; in this C/C++ code as part of a comment?

int a=1;
//some comment \
a++;
printf("%d\n",a);

And what about this?

int a=1;
//some comment ??/
a++;
printf("%d\n",a);

Yes, TextMate does it.

Answer 3

VC6, Visual Studio 2003, 2005, 2008, 2010 all do.

Kate (3.4) only highlights the first test, fails hilighting the second test

// hello folks \
int a = 0;

// hello folks ??/
int a = 0;

Answer 5

Slickedit - yes

KDevelop - yes

QT Creator - No

CodeBlocks - No

Answer 6

vim 7.2 sees it as a comment, and gcc 3.4.3 compiles it as a comment.

Answer 7

XCode and CodeWarrior handle it properly. (But not the trigraph, lol.)

Answer 8

emacs 22.3.1: No to both, sadly

Answer 9

Xcode sees the first as a comment, the second not.

Answer 10

Good question! I was going to ask a question about this until I found this one.

The Visual-DSP++ IDE from Analog Devices does not highlight either comment when writing in assembly or C. For example:

r1 = dm(pPointer1);      // Store pointer to r0\
r0 = lshift r1 by -16;   // Not highlighted as a comment but DOES NOT EXECUTE.
dm(i0,m1) = r0;
dm(i0,m1) = r1;
